The Alberta Mountain forestsecoregion lies entirely within Canada and almost fully within the province of Alberta, but hugs the Alberta-British Columbia border from Banff northward to Jasper and Kakwa. The ecoregion is classified within the Temperate Coniferous Forests biome.

Mean annual temperature in the Eastern Continental Ranges is 2.5°C, mean summer temperature is 12°C and mean winter temperature is -7.5°C. Precipitation increases from east to west and also with elevation, from 600-800 millimetres (mm) per year. Valley regions are marked by warm, dry summers and mild, snowy winters, and subalpine areas have cool, showery summers and cold, snowy winters.

This region covers the Rocky Mountains of Alberta, incorporating the eastern flanks of the Continental Ranges. The major peaks cluster around the Columbia Icefield, the largest icefield in the Rocky Mountains. The ranges themselves are linear with great cliffs and precipitous faces of thick sections of gray carbonate strata, and peaked by rock outcrops.

Reptiles

There are only two reptilian species present in the Alberta mountains forests: Western terrestrial garter snake (Thamnophis elegans) and the Common garter snake (Thamnophis sirtalis).

Amphibians

There are merely four amphibian taxa present within this ecoregion, namely: Long-toed salamander (Ambystoma macrodactylum) and the anuranAn amphibian that has limbs but no tail (includes all frogs and toads) species Western toad (Anaxyrus boreas), Columbia spotted frog (Rana luteiventris) and Wood frog (Rana sylvatica).

Conservation Status

Habitat Loss

Approximately eighty percent of this ecoregion is considered to be intactThe condition of an ecological habitat being an undisturbed or natural environmenthabitat. Major road corridors in valley lands with major outdoor recreation facilities and town sites are primarily responsible for loss of habitat.

Ecological Threats

Expansion of road systems and recreational activities pose a major ongoing threat. An earlier review of Banff National Park recommended major changes to recreational and town site development in the park, which would mitigate some habitat loss in this ecoregion over the long term. These recommendations have generally been accepted by the Canadian federal government. Attempts are also underway to begin adding structural elements to the trans-Canada highway, which passes through Banff National Park, to reduce wildlife-auto collisions, although the highway is also undergoing a major expansion. Coal mining adjacent to Jasper National Park is a potential threat to the integrity of this protected area.

Priority Activities to Enhance Biodiversity Conservation

Governmental agencies should write no grazing leases for below market rates, in order to discourage impairment of marginal rangelands.

No net increase in town site size in the major protected areas.

Increase control of recreation activities; limit access to trails and close off parts of the trail networks on a seasonal basis to provide less disturbance (and interaction) with wildlife such as grizzly bears.

Relationship to Other Classification Schemes

This ecoregion , designated as NA0501 by the World Wildlife Fund, covers the Rocky Mountains of Alberta, incorporating the eastern portion of the continental Ranges (TEC 207). The forests of this region cover the Subalpine East Slope Rockies (1), Montane Douglas-fir and Lodgepole Pine (5), and Tundra.
